Description
Multi-circuit power analyser for single or threephase systems installable on panels or DIN rails. Manages current input via two current transformer blocks connected with RJ-11 connectors.
The EM270 is equipped with a LCD display with controls to display measurements and configure the system, a RS485 port and two pulse outputs or two RS485 ports for daisy chain connections.
Benefits
• Reduced installation time and errors. Equipped with detachable terminals for all connections, with possibility of requesting pre-wired cables (optional). Connected to two current transformer blocks with two cables fitted with RJ-11 connectors. For connections in cascade of multiple EM270s the voltage reference is required only once.
• Installation flexibility. Suitable for panel or DIN rail mounting.
• Granular analysis. It provides total measurements or single circuit measurements (up to 2 three-phase circuits or up to 6 single-phase circuits).
• Specific software. The UCS proprietary configuration software enables rapid configuration and the display of all measurements. The software and subsequent updates are free.
• Tamper-proof. Configuration access can be locked. The terminals and display can be sealed.
• Self detection of primary current of the TCD (the dedicated current transformers).
Features
• Up to 2 three-phase circuits or 6 single-phase circuits managed simultaneously.
• Up to 630 A input current via solid-core current transformer blocks (TCDxX or TCD0W).
• Three installation configurations: on DIN rails, mounted on panel of 72 x 72 or 96 x 96 (with optional adapter).
• Single circuit measurements: V, A, W/VA/var, PF, kWh, kvarh. Virtual circuit (sum or difference) measurements: W/VA/ var, PF, kWh, kvarh.
• Display of electrical variables: 3 digits. Display of energy meters: 7 digits.
• Accuracy: better than a combination of a class 1 meter and a class 0.5 current transformer.
• Easy connection function.
• Up to 20 EM270 connected in cascade.
• RS485 port.
• Optional outputs: additional RS485 port for chain connection or two pulse outputs.
• Self power supply via voltage inputs.
• Detachable terminals and sealable terminal caps.
• Configuration via keypad or UCS configuration software.
